media: i2c: ov5695: Fix randbuild error

If VIDEO_OV5695 is y and V4L2_FWNODE is m, building fails:

drivers/media/i2c/ov5695.o: In function `ov5695_probe':
ov5695.c:(.text+0xf4c): undefined reference to `v4l2_async_register_subdev_sensor_common'

Select V4L2_FWNODE like OV5675 does.

Fixes: 39aac60bb992 ("media: i2c: ov5695: Modify the function of async register subdev related devices")
